Talk To Me About FI, Single vs. Twin vs Centi vs TVS

had one of those kit and they are real thurd. turbo is way off on turbine side, single t4 simply dont cut it for a coyote. engine is so chocked-up by this turbo that it has a hard time revving up to 6000 rpm... piping is shitty at best, fitment is a nigthmare, you end up with piping hanging way too low and hitting the subframe... i would buy on3 product wayyyy before buying another hellion kit.

First time I have heard this, you may have gotten a kit that was made on a Friday. I had a Hellion single kit with a 7675 Precision that I bought though Lethal. I will say I felt the kit was well built and with being able to utilize the factory manifolds was great. There are definitely limitations with the kit. Im my opinion the A2A is undersized, the fact that the MAF is a draw through rather then a blow thru is an issue. But in my opinion it was a great kit.

I opted for the Centri option after alot of back and forth. I am in the process of a F1-A install. For now I will be utilizing the factory A2W with plans for a A2A upgrade with a 01' Cobra intake with I already have from a Turbo kit. I will be running E85 with twin 465 pumps and a full return style Fore fuel system, ID1000's injectors. Car has ARH LT's with full 3" to back. I wanted something different then a PD blower and didnt want the headaches of a Turbo. I have been in a F1-A Cobra and its a wild ride when boost kicks in. I am looking to make around 750rwhp with around 25-27psi of boost. I know the Procharger intake is gonna hold back some power.

You aren't talking about a single hellion kit for a coyote. The post you quoted is 100% on the money. Absolutely the worst way to spend $5k. Kit is garbage plain and simple.

I ran the hellion single, Paxton and now the On3 kit. I really like the On3 kit, but the Paxton is good also. My biggest issues with the Paxton is the 6 rib belt and all the couplers for the charge pipes. Both issues can be fixed, but by the time you upgrade everything you'll wish you went turbo.

I opted for the F1 as I feel it will be less headaches then Turbo. I have a cog set up so no belt slippage issues, with the cog I have the heavy duty bracket so bracket flex is eliminated. I like the idea of a different setup and there is absolutely no beating the sound of a F1-A. That's what's awesome about this hobby, there is something for everyone. Glad the On3 has worked out for ya.

I would run ID 1300 injectors over ID1000 injectors if your going E85 which will need more than 1000s with a F1A

OP there is nothing wrong with going with a higher stall converter. With a 2400 stall you wouldn't even notice a difference from stock in daily driving. Only when you stomp on it from a stop will you notice a difference. Could probably handle the extra fluid heat with just a deeper aluminum trans pan and not need an additional fluid cooler.

A higher stall converter would almost be required with a centri supercharger and those aren't even noticed in daily driving either. They drive like stock until you get the rpms up.

IMHO perfect combination for what you're talking about doing with the car. Will drive like stock until you decide to put the power down and since you're not in boost unless you want to be there is very little wear and tear on the engine making for great reliability.

I had a Yank 3600 in my 98 Z28 and it ruined the car for me. Don't get me wrong it was fun off the line and messing around but when I wanted to go for a cruise with the wife it was miserable. Some of the hills here are miles long so you are constantly on the convertor droning.

Was that converter locking? I run a PA 2400 locking converter in my 04 GT. Flashes to 2600. No noise ever and not much extra heat when cruising due to the lock up. I veiw any stall above that as street racing/race only.

I have a 03' Cobra I bought new. I have had a ported eaton, Kenne Bell, single 78mm.
I've also have an 88 5.0 Vortech.
I had a 2012 GT with Procharger that was waste gated and 3.73s, manual. I have a stock 2013 GT500.

Out of it all:
* Most fun on the street light to light, KB Cobra so far. I assume the 13' gt500 will be right there with mods.
* The Procharger with a waste gate and 3.73s is a very very very close second to a PD blower in my opinion. Not as violent though.
* Single turbo is the most top end rush/ violent. The KB would break the tires loose in 2nd just stabbing the gas. The turbo will break the tires loose at 70 mph as the turbo spools.

Hi OP, I'm in the crossroads of twin-turbo hellion or procharger kit. The only difference is that my older sn95 is not a daily. I do agree with higher stalls not making cruise worthy. Some of the hellion comments in here are not comforting though...

I think my heart says turbo but my practical side say PD. I also think that the money I spend would be better put towards a GT350 or GT500 or Vette. I get bored with cars. I change them quite often.

I have read a lot of bad things about the single turbo Hellion. My car is a garage queen that I bought used.

What does everybody think about it having 39k miles? Is it too late to boost?

A positive displacement like the Whipple/VMP/Kenny Bell will probably be your best bet I think. They don't fill up the engine compartment like a centri would, and will make good power down low without having to worry about a converter change. You would make big power gains across the whole rpm range. Might want to upgrade your rear tires though.
